Referring to Fig. l, it will be noted that the letters A-B and Cv-D are .applied to show the fabrics or webs knit on the front and rear beds, respectively, it being well known that these webs are joined atB-C and at VA-D (although this drawing, Fig. 1, omits many wales between these points). vIn roundand-round knitting, a complete course is knit in the order A-B-C-D, as shown by the lowermost course 16, thisbeing the last course of the to e,.as noted inFig. 3. Y In knitting the split sole-in this -particular example the orderof knitting is approximately, starting `with the first yarn, from A forward on the` front bed to the'suture'needles, back-on the same bed to A, forward on the rear bed from D to the suture needles, back on the samebed to D, and then a change ofyarn. The second.' yarn will be introduced atthe suture needlesY on the front bed kand knitV forward to` B,v

back on the rearbed from, C to the suture needles, forwardon the.' same bed to C, and

then back on theA frontfbed to the suture needles where the yarn willfbe changed.v The first yarn will then be brought into action and the operations repeated. lVhethen the Y operations start withthefirst or second yarn is immaterial andit'is likewise immaterial` Vas to the point ofY starting theoperations. The

sequence of knittingghowever, by which the suture needles'are operated V1n alternation to produce al'sutur'e ofthe character disclosed herein, illustrates theprifnciples of myinvem tion and should be considered `in Vpreference tothe particular example herein disclosed which is but a singlevpractical application ofk my invention.- 'In this 'case am, therefore, starting to knit the suture: with theseCnd yarn which is brought into actionv at 17 at the suture needles on theinner side of the front bed.r In F 1, 4the wales knit bythe suture needlesar'e identified by the reference numerals appliedtrto said needles, namely, 12,13, 14,` 'and 15, respectively.

I claim:

1. A suture' between two knit fabrics comprising two adjoining wales in which the yarn Y of one fabric alternates with the yarn of the other fabric, each yarn being crossed upon 'in said two itselfy by being knit successively wales but in opposite strokes. Y

2. A knit suture connecting two knit Webs eachof different yarns, having plural suture Wales, one yarn*V in each suture course being crossed upon itselfv by being knit on one su- `V ture needle 1n one dlrection and onanother Y l kcourse being crossed upon itself. bybeing l v of the other adjoining web, and the 'yarninV i eachsuture course being crossed upon. itself suture needle in the opposite direction.

3.l A knit suturev composed-of plural wales i Y connecting two knit webs, in which the suc-A v cessive suture coursesare`r composed of altersutured, fabrics of this ,Y 'l

nate yarns and the yarn in each suture-course crossed upon itself bybeing knit in opposite directions. i 1 y 4. A tubular knit fabric composed of-plural Webs connectedby knit sutureseach su- Y Vture comprising plural wales, the alternate courses of the sutures having the yarn `of one f adjoining web andthe intermediateV courses having the yarn of the .otheradjoining Web, and the yarn forming the wales in each suture in opposite directions.

5. A tubular knitfabric composedofplulral websconnected by knit sutures, leachV su- Y ,Y ture comprising plural.Wales,the.alternate courses ofthe sutures being 1 composed of vthe yarnof one adjoining web andthe intermediate courses being composed vof the-yarn by being knit part in one direction andpart in the opposite'direction.

-6. A tubular knit fabric composedof plu'- ral webs connected by knit sutures, eachsuture'comprising plural wales',the'alternate courses of the sutures being composed o f thel yarn of one adjoining web and the intermei diate courses being .composedi of the yarn WALTER QF. RonsToN. l
